HSTS232050B751 from HXY MOSFET, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | I/O1 | passive | Protected line 1, connected through a TVS diode to common pin 3; the device protects one bidirectional line or two unidirectional lines with VRWM 3.3V max. |
| 2 | I/O2 | passive | Protected line 2, connected through a TVS diode to common pin 3; the device protects one bidirectional line or two unidirectional lines with VRWM 3.3V max. |
| 3 | COMMON | passive | Common node of the two TVS diodes shown in the circuit diagram, shared by pins 1 and 2. |
